Correlation between vessel diameter and pericyte morphology.

Vessel diameter (range)	Pericyte trunks		Pericyte branches
	Number	Length (µm)	Number	Lenght (µm)
>30 µm (74.8–31.9)#,$	3.9 ± 0.3#,$	12.5 ± 1.4#,$	1.0 ± 0.3#,$	5.4 ± 0.5
<30> 10 µm (29.1–10.5)	2.7 ± 0.2*	17.2 ± 1.5*	0.4 ± 0.3*	5.7 ± 1.2
<10 µm (8.9–3.0)	2.0 ± 0.2	35.7 ± 4.7	0 ± 0	n.a.

Z-stacks were taken of at least 3 different tumors and vessel diameter, number and length of pericyte trunks and branches measured. ^#p < 0.05 for >30 µm versus <30> 10 µm vessels; ^$p < 0.05 for >30 µm versus <10 µm vessels; *p < 0.05 for <30> 10 µm versus <10 µm vessels. Data represents mean ± SEM of at least 3 cells in 3 different tumors. n.a. = not applicable.
